it.unibz.inf.ontop.owlapi.connection.impl

Class DefaultOntopOWLStatement

java.lang.Object

it.unibz.inf.ontop.owlapi.connection.impl.DefaultOntopOWLStatement

All Implemented Interfaces:

OntopOWLStatement, OWLStatement, AutoCloseable

public class DefaultOntopOWLStatement
extends Object
implements OntopOWLStatement

A Statement to execute queries over a QuestOWLConnection. The logic of this statement is equivalent to that of JDBC's Statements.

Performance Note that you should not create multiple statements over the same connection to execute parallel queries (see DefaultOntopOWLConnection). Multiple statements over the same connection are not going to be very useful until we support updates (then statements will allow to implement transactions in the same way as JDBC Statements).
